Offensive Gap and D-Line Technique Designations

Offensive gap designations are identified as the gaps between each offensive lineman and tight ends. Each gap between the offensive linemen positions are designated with a letter.

For example, a double A-Gap blitz will have two defenders blitz in the two gaps between the center and guards.

Defensive Line Technique Designations

Defensive line technique designations are identified by numbers where exactly a defensive lineman is positioned across from an offensive lineman.

For example, a 3-technique defensive tackle will be aligned on the outside shoulder of a guard (away from the center), whereas a 5-technique defensive end will be aligned on the outside shoulder of the offensive tackle across from him.
